TYPOGRAPHICAL CASTING-MACHINE.

Application led December 1i, 1914. Serial No, 874,960.

To all whom it may-concern: f'

Be it known'that We, CiiAiiLEs HOLLIWELL casting machines, particularlythose l.lmown commercially under, the trade mark flinotype, and it hasfor its Aobject' to provide .means whereby, for particular classes ofwork involving the casting of typebars of different bodyv dimension, thetrimming l:;.ives can he automatically adjusted in accordance with thosebody dimensions. i

Among the ahovenamed classes of work in connection with which thepresent invention could .be advantageously employed,

there. may be mentioned the casting of'typefhars, hereinafter termedAslugsf suitable for the printing of Christmas cards, and auctioneersand various other catalogues, in which one item such for example as, inthe case of a Christmas card, the name of the sender would be printed inlarger type than would be the address or legend appearing on that c ard.v

The different sized slugs, say two sizes, involved in the use of thislinvention, would hotli he cast in the same mold, the cap of which wouldbe'giooved to aIdepth which,

measuring from the bottom of those grooves to the' opposed face of themold body, would frespond with the body dimension of. theV sli-ig suitedto carry the characters of the largest hody dimension, and the distancebe-v tween the surface of the inold cap between those grooves and thesaid opposed surface of tli mold hody would represent the body dimensionof the slug appropriate to the Specification of Letters Patent.

PatentedAiig. 1, 1'916".

off lof-what have, in the past, been termed two-line letters, and thepresent invention involves the use of l trimming knife adjustable insubstantialy the same manner.

Heretofore these two-line-letter knives have` had their, longitudinalmotion restricted by their paths being intercepted by the twolineletters which it was intended should be retained on the slug, and whichletters, if

the movement of the 'knife Werenot so restripted, would have. been shornolf by. that kni e. 'l I The present invention involves among other newfeatures, novel. means .whereby a knife Ypreviously set f or trimmingslugs of one body dimension, can be released, by

overhanging projections cast. onthe slug, to

allow -it to assume the position .necessary tor trimming slugs ofanother b'ody dimension, but these projectionsl unlike thebefore-mentioned two-line letters, are pro-l vided solely for thepurposeof controlling the adjustment of thc `knife and are-shorn off by thelatter after theyfhavefulfilled' .that function.

The invention will VVnow be described by' refe-rence to wliich:-' iFigure l is a front elevation-of Vsufficient of a typographical castingmachine-to show' the application thereto of the present invention; Figs.2 and 3' are plans of Fig. 1, showing the devices at respectivelydi'erent stages of their operation. i Fig. 4 is a perthe accompanyingdrawings in spective 'view of the improved movablev knife; Fig` 5 isaperspective. view and Fig.

The parts of the machine illustrated in the. drawings which are ofordinary construev tion, and -thus constitute. nofeature of the presentinvention, are, by way of distinction, indicated in chain or dottedlines.

According to the'present invention. thc adjustable-knife, which, as acomplete en tity, is hereinafter identified by the refer! `ence numeral1, is formed in what mai-f he regarded as two sections, these in F ig.AMthe.-

ing clearly 'distinguishable hy the nunierals 2,3 respectively, thetrimming edge of the section 3 being in advance of that of the sec'-tion 2 and serving for trimmingislugs of smaller body dinension'timnthose to be trimmed by the seetion 9.. By the term in advance as justemployed is ineant a position nearer to the stationary or fixed knife 14(Figs. l, 2. and 3).. In the arrangement each othe'natf'an ahrupt'angle.

, The knife 1 is arranged' to slide vertically v in a guide block 8 soas to bring one or the Aother of its sections i'nt-o active position oropposite the stationary knife 4i, a spring la tending constantly toraise the knife to its lipg'ierlnost position, and :L bar 1b, connectedto thelower end of the knife and actuated by some suitable part of themachine, Abeing adapt/odioreturn the knife to its low'errnost positionagainstthe action of the spring.

tendingstad 6 (Figs. 1, 2 and 3)' which is The. knife 1 has fixed to ita laterally excapahle of moving in a vert-ical groove 7 in a'gliideblock 8 in which Vthe knife l capable ef sliding ina vertical directionin ie spense to the action thereon of the aforesaid can! and spring. Theguide 8 is, in Athe usual manner, attached to the vSo`called knife-block3 Vwhich is in turn attached to the vise frame l0, towhich also asordinarily isvseeured the beforeementio'ned stationary knifef.Y y

At the Vrear vof the groove? there 1s provided la horizontal slidinglatch '1l which can he .projected into the groove, as shown in Fig. 2,and withdrawn from it as shown in Fig. '3, for engaging;'withl the stud6, shown in the former figure, and releasing it as shown in the latter4ligure. When .the latehll projects into the groove. 7 above the sind 6Athe movable' knife l is held by' the engagement of the forrner. with thelatter in its depressed position, asv indicate-d bestin Figs?, and it iswhile the kn'ife is in that position that it effects the trimming oftheslug-s hearing charactersl of the smaller body' dimension; so long asthis engagement of the iatch 11 and sind 6 continues, the section 2ofthe knife cannot come into operation, hat when the latch l1 iswithdrawi'i into the position in which it is shown in Fig. 3, the

meses@ knife l is raised by the aforesaid spring and the section Lthereof is thereby brought into operative posit-ion to i1-ini slugshearing characters of the larger bodyA dimension.

The slidingr Vlatch 1l is in pivotai Conner:L 70 tion' with a plate 12adapted to turn about the vertical pivot 13 in fixed relationship to the`luide hlork 8, this pivotal connection being effected by forming a niekor reduced portion of the-latch ll wh'ichis embraced -7'5 by a slot 14in the plate i2. A blade spring 15 fastened at one end to the guideblock bears :it-rits otherend on the rea-r end of the latchll insuchmanner as to constantly tend to hold the latch in, or return itto, its-50 normal foremost position in'which it is in engagement,` or ready toengage,-.with the stud (3. Theforward end of the latch 11' is inclinedat its upper side as indicated at 1,6 in Fig. 2, -so that when the stud6, during g5 the' descent of the' knife. 1, moif'es'into con` tacttherewith (the Said latch being then in its foremost position) it,thestud, pushes 4 the latch 11 rearwardly 'out of its' path, and

the said latchl after the stud has thus cle- 9o scended past it isiminediately-z` returned 'oy its spring 15 into its foremost'. positionto again operate to prevent the',"ll:n if e`v 1l reach- Lingr its higherposition. The, forwrdinove nient of the latch 11 under the tiction ofthe95-VY spring 15 is limited by'theriglibhandiedg'eo f the plate 12,which, vby, abutting against the rear side of the gnideblockl' 8,-a'sindi`` cated in Fig. 2, serves-11s a; stop for this pur-v from `theposition -in which it isfs'liowii.in

Fig. 2 to that in 'which it is shown-in Fiel 105- This 'pivo'ted 'plateV12' isadaptedto bel turned on its pivot 13v`in opposition totherinflnenee'of the spring-"llo bythe knife-releasing projeetionsnext tobedescribed, castfor thatspecial purpose oh these-id slugs.

In certain matrices-employed for casting slugs bearing characters 'ofthe. larger 'bodyv Y dimension, forv example, 'punctuation rnzit=l rices195o-oh as-are shown in Figs?? and 6 oren spaces 20su`ch as are shown inFig. 'I Us.

or character matrices having descenders snc-h asA the is, there areprovided S119` pleinentalf cavities 21Whieh are instr'umenj` tal inproducing'the'.aforesaid overhanging knife-releasing projections 22 onwhat may 12e he regarded as.the descendervside of the' resnltant, typecharacter cest 0r. spaee produced. Each vof thesesupplemental 'cavities21 is divided from' the main formative cavity 23 hy a sour-.24 whichleaves .the 12' aforesaid resultant projection 22 attnehed totheslng'il' by a. thin and readily breakeole neck 25.

Vlhen thelsupplemental cavities 2i are formed on the en spaces Q0, asshown in Fig.

7, these latter are provided with other cavities 26 aliiicd with tlie.formative cavities 23 of the character matrices and divided from thesaid supplemental cavities by spurs 21 as in the example shown inFigsnvand 6, but the cavities 2G are not sufficiently deep to producesurfaces of' printing height; oonsequently the projections cast on theslugs in these .cavities cannot make impressions on the printed sheet,the said projections serv- 'ing merely tol provide a temporary supportvfor the wei-hanging knife-releasing projections 22 cast thereon. i

' In the case of slugs vhaving characters of the smaller body dimension,there is' no necessity for the knife 1`-to be moved from its lowestposition andeonseqiiently there aie no projections 22 cast-on thoseslugsA and therefore nothing to cause'the plate 12 to' turn on itspivot; consequently during the forward movement of the mold wheel, the

' latch 11,' then-in 'its forward voroperative position,is notdisturbed,j and for the time being retains the knife'l its-lowermost'po-'sitioiL with the section 3 t `ere`of in position to effect the trimmingof the s'aidslugs.

For effectively carrying outthis invention there need not be more thanone of the projections 22 caston each 'sl'iigrhving characters ofthe'larger body dimension, andif the line, in-connection with which theprojection 22 is cast, contains no vpunctuation marks or descende'is,then the said 'ipiojections 22 can be .produced from one of! theaforesaid en spaces 20 which can-be inserted` into the composed line ofmatrices at or near eitherend thereof. u To enable vthe machine totrim`slugs of varying body dimensions, that'is to say,.

justment, however, in these fourhguresvis" shown as restricted to theupper section 3,Y

but it4 is to be `understood that if desired corresponding adjustmentofthelower -section 2 may he provided for` .as an alternative to or inconjunction with, the adjustability of the upper section 3. In each-oftheA arrangements now under, review the`A knife 1`is formed of two mainportions 2G and 27, the former bearing the before-described knifesection 2 and `the latter bearing the knife section' 3.

.In the construction'shown in Fig. 9 the knife portion 27 isA capable ofbeing secured 'in different positions on thepoi'tions 2G, by means ofone or more clamping screws 2S,

and-when these screws 28 are released the part 27 can be finallyAadjusted on the part 26 by ineans of set'sciews 29 threaded in the lastnamed part. and bearing against the right-hand edge of the part 27.After siich'adjustment by the set-screws 29 the two parts 27, 2G canlie-rigidly secured to gether by tightening the clamping screws '28.

In the construction shown in Figs.' 10

and11 the part 27 is lield, to the part 26 by two'screws 30 threaded.into the latter part, the heads of which are counter-sunk into theformer part, and 4the pat` has vthreaded intoit thej stems ofv set?screws 31, the heads. 32'of which abut Vagainst the right-hand side. ofthe part 27,

these set-screws 31 Abeingvaljusted from theright-hand side of theknifebv a screwdriver engaging with slots or n icks (see'par--vticularly Fig. 11) in the ri'glit-liand ends of their stems. To enablethe part 27 to he adj usted relatively tothe part 26 the screws 30 arereleased and the setscrews 31 are' screwed .more or `less into Athe part26 to` Y obtain the desired relative positions between the operative.faces 3, 2 of the parts 27,26, 'and after this adjustment has beensecured the two partsinay be'iimlyisecured in the positions so varrivedat by tightening the screws 30, which at the Sametime serve. 'to

AVlock the v'set-screws 31 'against vaccidental i'o'- tation.

In the construction shown inA Fig. 1 2 the part 27 is held totheipart26'by tia'oscrews V 3Q the sem of each. ofwhich is threaded into nicks34 whereby they canbeadjustedso as 'to project more rless from the part26. YTo

lockV the bushesinany position to which they may be adjusted in the part26 there are provided short headless screws threaded into thesame holesras those infwhic-h the said bushes' are themselves adjustable. andwhen those screws are jammed against the right hand side vof the bushes33. both such parts are locked against accidental displacement.

ics

In this arrangemeiit the' left-hand ends of the bushes 33 serve. forsupporting the lpart '2.7

against the tightening pressure of the screws 3th, in thesa'memanner asdo the screw-heads 32 in the 'exampleillustrated in Figs. 1()V and 11..Jiaving described our invention we de claie thatv what we claiml anddesire to secure by Letters Patent. is l 1.
